GaperGuide offers a self-driving audio tour of Grand Teton and Yellowstone national parks. All you do is rent one of our Guides, put it on your dashboard and plug it in to your cigarette lighter - the Guide does the rest. It tells you all about the parks while you drive. The tour is based entirely on where you want to go and it goes at your pace. There is no required route or timing. You will laugh and learn as the Guide's characters talk about the history, science and interesting facts behind the park. They even point out where the animals hang out, the good hikes, picnic areas and bathrooms. The Guides are available for $45/day for the whole carload of people. You will be able to pick a Guide up at our partner stores near every entrance to the parks, and drop it off at any other.
